November, 14th 2010 Automotive grade AUIR3315(S) PROGRAMMABLE CURRENT SENSE HIGH SIDE SWITCH Features Product Summary Load current feedback Rds(on) 20 m max. Programmable over current shutdown Vcc op. 6 to 32V Active clamp ESD protection Current Ratio 2800 Input referenced to Vcc Prog. Ishutdown 3 to 30A Over temperature shutdown Vclamp 40V Reverse battery protection Lead-Free Packages Description The AUIR3315(S) is a fully protected 4 terminals high side switch. The input signal is referenced to Vcc. When the input voltage Vcc - Vin is higher than the specified threshold, the output power Mosfet is turned on. When the Vcc - Vin is lower than the specified Vil threshold, the output Mosfet is turned off. A current proportional to the TO-220 DPak power Mosfet current is sourced to the Ifb pin. Over AUIR3315 Pin 4 and 5 fused current shutdown occurs when Vifb-Vin > 4.7V. The AUIR3315S current shutdown threshold is adjusted by selecting the proper RIfb. Either over current and over temperature latches off the switch. The device is reset by pulling the input pin high. Other integrated protections (ESD, reverse battery, active clamp) make the switch very rugged in automotive environment.
